How Acoustic Camera Measurements can help to increase the Acceptance of Wind Turbines

摘要

This paper introduces the X-Eptance project of the HAW Hamburg with the goal of creating a wind turbine sound database as a basis for virtual reality simulations of wind parks. This should give residents the chance to get tangible information about the planned wind park in advance with the objective to take away their fears by creating objectivity and to increase acceptance. Also the basic properties and functionalities of sound source localization using beamforming and the Acoustic Camera are explained in this paper. With this acoustic measurement method it is easy to record, identify and localize sound sources on wind turbines. This information can be used to create a wind turbine sound database, which can be used for the auralization of planned wind parks, as well as a set of reference sounds for the monitoring of wind turbine condition.
